摘要： A surface modified and functionalized carbon black for use in a rubber compound suitable for tire tread compounds which can be described as a surface modified low hysteresis carbon black. The modified carbon black contains a chemical consisting of at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage. The surface modified low hysteresis carbon black in a representative rubber tire tread compound shows improved rolling resistance, improved wet traction, and improved or maintained abrasion resistance, being superior to compounds containing N234 carbon black or silica. The improved tire rolling resistance obtained by using a compound containing a surface modified low hysteresis carbon black is highly desirable for reduced CO2 emissions, reduced pollution, sustainability, and protection of the environment.

摘要： A method of producing a surface modified low hysteresis carbon black or a refined surface modified low hysteresis carbon black compound includes treating a surface of a low hysteresis carbon black with about 0.1% weight by volume to about 50% weight by volume of surface modifying agent in a solvent, and heat treating the surface of the low hysteresis carbon black following the treatment of the surface with the surface modifying agent to form a surface modified low hysteresis carbon black compound, wherein the surface modifier includes at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage.
